4-Spoke Direct Mount for SRAM GXP Cranks
Looking for a different spoke design or a size that is out of stock? Be sure to check out our new 5-spoke direct mount for SRAM GXP: right here
These are Direct Mount chainrings for SRAM GXP crank. This will replace you existing chainring and spider, which is attached via 3 bolts on the back side of the spider near the spindle. You will use these same 3 bolts to attach the SDM ring.
SDM chainrings fit on SRAM cranksets with removable spiders: S2200, S2210, X9, X0, X01, XX1, X1 1400, Truvativ AKA Cranksets (GXP version), and newer S1400 (or X7) . If the crankarm and the spider are all made from the same piece of aluminum it is not removable.
Chainline is 50mm on all rings (on a GXP or BB30 long spindle crankset). All chainrings feature our Drop-Stop tooth design and are made from 7075 Aluminum.
These can also be used on a BB30 / PF30 long spindle crankset -- the 3rd product picture shows you how to determine if you need this ring or the Short Spindle BB30. This SDM ring is dished in ~6mm, whereas the BB30 short spindle ring is flat.
Use a 10 or 11 speed chain. If using a 9 speed drivetrain, plan to use a 10 speed chain (it will shift fine), as the 9 speed chain fits too loosely on the ring.
Product weights: 26t - 53g, 28t - 60g, 30t - 68g, 32t - 74g, 34t - 83g, 36t - 90g
